Proccessing cerate-zirconate nanopowder at supercritical conditions via batch-wise reactor system / Nafisah Osman and Mohd Azlan Mohd Ishak

Protonic conductors of ceramic perovskite-type oxides (ABO3) have captured attention of researchers worldwide for technological purpose in fuel cells, batteries, steam electrolyser, etc. The best candidate amongst them is the perovskite-type oxides of Ba(Ce,Zr)03 which is known to exhibit high mecha...
